I've also heard from some people that the approach might be less "what can
we add to rails core" and more "what can we take out of core and turn into a
plugin".  (I think Dave Thomas said that on the RoR podcast at one point).
So, I agree with Eric that it's unlikely.  I'm not sure I'm totally bought
in on making everything a plugin, but there are pros and cons to each
approach.

Although I haven't tried it, this might be worth checking out:
http://blog.labnotes.org/2006/07/03/assert_select-plugin-for-rails/

The word is that it's going to get folded into rails core:
http://glu.ttono.us/articles/2006/09/03/assert_select-included-in-core-assert_tag-deprecated

Although it doesn't appear to check which partial is rendered, it goes a
step further and inspects the returned html.  So, arguably that's a little
more brittle, but it appears powerful enough that you could see if the
output your partial was expected to display was in fact returned.
